WebAug 23, 2024 · The molecule “feeding” the citric acid cycle is acetyl-CoA and it can be obtained from pyruvate (from glycolysis), from fatty acid β-oxidation, from ketone bodies, and from amino acid metabolism. Molecules from other pathways feeding into the citric acid cycle for catabolism make the citric acid cycle ‘cataplerotic’. WebThe citric acid cycle is a metabolic pathway that connects carbohydrate, fat, and protein metabolism. The reactions of the cycle are carried out by eight enzymes that completely …

WebAcetylcoenzyme A initiates the citric acid cycle. The citric acid cycle releases sixteen hydrogen atoms. These hydrogen atoms must be transferred through the eight steps of the citric acid cycle. This is carried out by nicotinic adenine dinucleotide (NAD+). Each NAD+ is converted to NADH in three steps of the citric acid cycle.
WebThe citric acid cycle captures the energy stored in the chemical bonds of acetyl CoA (processed glucose) in a step-by-step process, trapping it in the form of high-energy intermediate molecules. The trapped energy from the citric acid cycle is then passed on to …
